The power of physical reasoning lies in its ability to explain a lot by knowing just a little. Here we'll establish the bedrock principles of physics and use them to investigate phenomena like drones, rockets, and the blinking of fireflies. By the end, you’ll develop a rigorous approach to describing nature and you'll be prepared to take on advanced topics such as quantum and statistical mechanics.
The study of physics-free motion.
Three rules to govern all of classical mechanics.
Change has a cost, and it is paid in energy.
How to keep things moving.
The grass is always bluer, if you run fast enough.
The science of staying still—from yoga to the justice of the sea.
An astounding fraction of modern physics stems from our understanding of springs.
The study of collective phenomena—more is different (but also the same).
